IMPROVEMENT lhl CARDlNG-MACHINES.

' Specification forming part of Letters Patent No.1 79,962., dated July18, 1876; application filed I April 18,1876. r

1'0 all whom it may concern: I

Be it known that I, JAMES 0. RYAN, of

Amesbury, in the county of Essex and State of Massachusetts, haveinvented a new and Improved Oarding-Machine, of which the fob lowing isa specification:

My'invention consists of an attachment to carding-machines for making nubbed and clouded or imitation printed yarn, the same being intermittentfeed-rollers, a knife for holding back the yarn or sliver, and awiperoll, by which the yarn is supplied to the (101T- er of thecarding-machine, and there combined with the stock, forming thegroundwork of the yarn.

Figure 1 is a sectional elevation of a cardingmachine with my improvedattachment, the section being taken on the line m w of Fig. 3. Fig. 2 isa section on line 3 y of Fig. 3. Fig. 3 is a top view, and Fig. 4 is afront elevation. v

Similar letters of reference-indicate corresponding parts.

A is the ordinary (letter of the carding-machine; B, a wipe-mwllich Iarrange below it in connection with a pairof feed-rolls, O and andD,-and a knife, E the knife being. arranged to close on the largefeed-roll between it and the wipe-roll by the spring 1* on therock-shaft G, from the arms H of whiehthe knife is suspended. The cam Ilifts the knife off the feed-roll by raising the arm J of shaft G, thecam being turned by the belt}; from the driving-shaft L.

The feed-roll G is turned intermittingly by the pawl M and theratchet-wheel N. This pawl is worked by the slotted disk 0 on thecam-shaft, which is adjustable to turn the feed-roll more or less,according to the amount it is desired to feed. The slivers to besupplied are drawn from the spool P. resting on and being turned by thedrum Q, which is turned by a belt, It, from the feeding-roll C.

By this contrivance the machine will make nubbed yarn with the webs anydistance apart, provided the cam-shaft be geared so that the speed maybevaried, the sliver being fed in full size when the knife is raised, andchecked back and stretched when the knife is closed on the feed-roller.It will also make clouded or imitation printed yarn of different colors,as many different colors as may be desired being employed, and beingseparated from each other by passing through different guideeyes S.

For making clouded yarn, the knife will be taken out when the attachmentis not wanted. The set-screw T fastening the arm J to the rock-shaft maybe loosened, and the pawl M shifted out of the ratchet, which willallowthe carding-machine to work the same as without the attachment. I

Having thus described my invention, what I claim as new, and desire tosecure by Let-.

ters Patent, is-
